Payam Norouzzadeh
Payam Norouzzadeh joined our group in 2010 after working at industry and
research labs for about six years. Prior to OSU, Payam worked at University
of Antwerp in Belgium on Graphene using first principles methods, at Kiel
University in Germany on parameter estimation of multifractal and stochastic
processes, and at Texas Tech University on Type VIII Clathrates and some
other thermoelectrics using first principles methods.
At OSU his research has been focused on developing a computational tool for
studying the charge and energy transport in nanocomposite structures. His
focus is to find an efficient method for solving a long lasting problem in
explaining the non-linear transport of charge carriers and phonons in
nanocomposites. This theory
can open a new landscape for studying and designing such structures.
